Are you getting the logon page? Try http://tplinklogin.net/ in place of 192.168.0.1. Also check your modem settings to see if it want a different IP address in a field something called like Ethernet IP address (sometimes 192.168.1.1) After factory reset, you use the default userid and password as all of the settings must be reentered including the new userid and password. You can also try the Tether app.

This page (http://tplinklogin.net/) doesn't load.

So 192.168.0.1 title is Opening... and change background color like this, but the page is not loading.

I try Tether app, but it provides much less setup options than I need.

The "like this" link is not working. Try cut and paste in your message. Not sure what you mean by changed background color. The tether app is limited in what it can do, which is both good and bad. Good it limits what can be done since it is another way into the router that can be exploited by others. Bad that it limits the owner. In your browser, clear history and cookies, then power cycle your router and try again.

Because "like this" is not a link... it is just a color example.

I clear history and cookies many times in my browsers (and other PC browsers), but did not help.

When I opened the devtools in browser, I realize this file doesn't loaded: http://192.168.0.1/webpages/locale/en_US/lan.js

I just got this message:

This page isn’t working

192.168.0.1 unexpectedly closed the connection.

ERR_CONTENT_LENGTH_MISMATCH

 

Can you open this .js file?

I cannot load the .js file as I get a 501 error. I can open just 192.168.0.1 and get my log on page for my Archer C8.

Yes, when I visited 192.168.0.1, the website redirect to http://192.168.0.1/webpages/login.html?t=1516243669548, and I just can see the background, no login option (I attached the screenshot).

I reset my router and I try to access the admin website on cable connection with router, but I have not succeded.

 

It sounds like your browser is redirecting. Most browsers have options to prevent a redirect. Google "stop browser redirects" for you specific browser and see if that does the trick. Also look for a file with that name on your system. Lets us know what works.

Try this, I hope it helps

 

In Chrome, press Ctrl + Shift + Delete. 

 

Go to Advanced tab, Select "All time" for time range, scroll down and check "Site Settings", then finally click "Clear Data"

Then reload the Router admin page
